188-188: Enhance the base64 validation regex pattern.While the regex pattern correctly validates base64 data URLs, it can be improved for better security and maintainability:
- The pattern should be anchored with
^and$(already done correctly).- The media type validation is expanded to include
application/octet-stream, which is good.- However, the base64 validation part
[a-zA-Z0-9+/]+={0,2}could be more strict.Consider using this enhanced pattern for stricter validation:
- const isBase64 = /^data:(image|application)\/(png|jpg|jpeg|gif|octet-stream);base64,([a-zA-Z0-9+/]+={0,2})/ + const isBase64 = /^data:(image|application)\/(png|jpg|jpeg|gif|octet-stream);base64,([A-Za-z0-9+/]{4})*([A-Za-z0-9+/]{4}|[A-Za-z0-9+/]{3}=|[A-Za-z0-9+/]{2}==)$/This improved pattern:
- Uses a more precise base64 validation that checks for proper padding
- Ensures the string ends properly with the base64 data
188-188: Add unit tests for base64 validation.The changes to the regex pattern require comprehensive testing to ensure correct validation of various base64 encoded images.
Would you like me to help generate unit tests that cover:
- Valid base64 encoded images with different media types
- Invalid base64 strings
- Edge cases with different padding lengths
- Malformed data URLs
188-188: Document the supported formats.The function now supports additional formats through application/octet-stream, but this isn't documented.
Add a JSDoc comment to document the supported formats:
+ /** + * Filters and validates image URLs, supporting: + * - Regular URLs (filtered through XSS) + * - Base64 data URLs with the following media types: + * - image/png, image/jpg, image/jpeg, image/gif + * - application/octet-stream + * @param {Object} props - Component props containing the src + * @returns {string} Filtered URL + */ export const filterImageUrl = (props) => () => {

188-188: Verify browser compatibility for application/octet-stream.The addition of
application/octet-streammedia type needs verification across different browsers to ensure consistent behavior.Let's check browser compatibility and existing usage:
✅ Verification successful
The application/octet-stream MIME type usage is safe and compatible.
The MIME type is used correctly within the data URL validation context and is well-supported across all modern browsers that the project targets.
